Abstract: Traditional cookstoves available in developing countries cause substantial air pollution due to inefficient biomass burning. To overcome this issue forced-draft models are employed. While forced-draft models can reduce emissions, they require an electric grid connection for the fan, limiting their accessibility. To address this, we have developed a thermoelectric generator (TEG)-integrated forced draft biomass cookstove (TIBC) that generates electricity for the fan, enabling clean cooking in off-grid areas. The power generated by the TEG runs a 12 V DC cooling fan, which keeps the TEG's cold side cooler and directs air into the inner combustion chamber through primary and secondary orifices. This increased air circulation enhances combustion, leading to reduced emissions and improved thermal efficiency. Experiments are conducted to evaluate the performance of TIBC using three common solid fuels (wood, peat, and manure). The results showed that the TEG generated a maximum power output of 6.30 W (peat), 6.12 W (wood), and 4.10 W (manure). Furthermore, TIBC significantly reduced PM2.5 and CO emissions compared to traditional cookstoves (TCS) and natural draft cookstoves (ND). The TIBC achieved its highest thermal efficiency (ηth), TEG efficiency (ηTEG), and collector efficiency (ηC) of 41.30 %, 4.30 %, and 33.96 %, respectively, when peat was used as the fuel source.
